ABSTRACT
The mechanism and instrumentation of an atomized liquid sensing system is presented, characterizing the dynamic polarization and ionization processes of liquid droplets in an electric field converged by one dimensional nanostructures. The microarchitecture implementing the mechanism is realized by microlithography technology. It is shown that the current amplitude is a function of both droplets’ flow rate and its chemistry; thus, one of them can be differentiated when the other is a constant. Further, the current-time spectrum responding to the vaporization and diffusion processes can enhance the differentiability. The methodology can be applied to atomized liquid sensing or liquid chemistry differentiation.

    Ions undergoing a reaction-diffusion process are susceptible to electric field. We show that a constant external field may induce a kind of instability on the state stabilized by diffusion in a reaction-diffusion system giving rise to formation of pattern even when the diffusion coefficients of...

    While lattice kinetic Monte Carlo (KMC) methods provide insight into numerous complex physical systems governed by interatomic interactions, they are limited to relatively short length and time scales. Recently introduced coarse-grained Monte Carlo (CGMC) simulations can reach much larger length...
